Question

The endpoints of CD are C(−2, 0) and D(4, 9).
The coordinates of the midpoint M of CD are?

Answer 1

Answer:

1, 4.5

Step-by-step explanation:

for midpoint

x₁ = -2, y₁ = 0

x₂ = 4, y₂ = 9

for midpoint

(x₁+x₂)/2 , (y₁+y₂)/2

(-2+4)/2 , (0+9)/2

2/2 , 9/2

1, 4.5

Answer 2

Answer:

The midpoint of CD is (1,4.5)

Step-by-step explanation:

The endpoints of CD are C(−2, 0) and D(4, 9).

To find midpoint , we use midpoint formula

$(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2})$

C(−2, 0) is (x1,y1) and D(4, 9) is (x2,y2)

Plug in the values in the formula

$(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2})$

$(\frac{-2+4}{2} ,\frac{0+9}{2})$

(1,4.5)

The midpoint of CD is (1,4.5)
